Clinical analysis of small incision minimally invasive approach in treatment of infected pancreatic necrosis / 中华外科杂志

Objective@#To investigate the safety and efficiency of small incision minimally invasive approach pancreatic necrosectomy in the treatment of infected pancreatic necrosis.@*Methods@#The data of 164 patients who underwent small incision minimally invasive approach pancreatic necrosectomy for infected pancreatic necrosis at Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from January 2012 to December 2016 were analyzed retrospectively.Among 164 patients, there were 102 male and 62 female patients.The median age was 46 years(ranging from 19 to 79 years). One hundred and one patients(61.6%) suffered from severe acute pancreatitis and 63 patients(38.4%) suffered from moderately severe acute pancreatitis.Following step-up approach principle, the surgical procedures were performed for 131 patients(79.9%) who suffered from sepsis which could not be alleviated via percutaneous catheter drainage(PCD). The other 33 patients(20.1%) who did not undergo PCD directly took small incision minimally invasive approach pancreatic necrosectomy.Preoperative CT images were used to determine the location of the lesion.The PCD puncture points or the points where the abscess was closest to the skin were chosen as the incision.Gradually, the small incision minimally invasive approach pancreatic necrosectomy were performed via cutting all layers into the abscess.@*Results@#The median time from the onset of symptom to first operation was 32 days(ranging from 23 to 45 days). The average hospital stay was 46 days(ranging from 29 to 103 days). The average number of drainage tubes placed was 4 pieces(ranging from 2 to 8 pieces). Ninety-two patients(56.0%) underwent minimal access retroperitoneal pancreatic necrosectomy. Thirty-six patients(22.0%) underwent minimal invasive approach lesser omentum sac pancreatic necrosectomy.Thirty-six patients(22.0%) underwent minimal invasive approach lesser omentum sac pancreatic necrosectomy combined with minimal access retroperitoneal pancreatic necrosectomy.A total of 148 cases(90.2%) were cured via minimally invasive approach pancreatic necrosectomy, 8 cases(4.9%) were cured after transfering to open pancreatic necrosectomy.The cure rate was 95.1%(156/164). The mainly postoperative complications included pancreatic fistula(25 cases), intra-abdominal hemorrhage(10 cases), gastric fistula (2 cases), duodenal fistula(4 cases) and colonic fistula(3 cases). The overall incidence rate of complications was 26.8%(44/164). Eight cases were dead after surgery and the in-hospital mortality was 4.9%(8/164).@*Conclusion@#In summary, small incision minimally invasive approach pancreatic necrosectomy is an effective way to clean up necrotic tissue, improve the drainage, reduce complications in dealing with infected pancreatic necrosis.

Abdominal packing for surgically uncontrollable haemorrhage.

Background: Using abdominal packs is often a life-saving technique for uncontrollable bleeding during operations. It prevents worsening of the hypothermia, coagulopathy and acidosis which usually accompanies massive bleeding till they may be corrected and the packs removed later. However, packing may be associated with a mortality of 56 to 82 % due to continued bleeding, intra-abdominal abscesses and the compartment syndrome. We follow a policy of early abdominal packing (considering it after a 6 unit intraoperative blood loss) before the situation becomes irreversible. Patients and methods: Between January 1997 and September 2008, abdominal packing for uncontrollable bleed was done in 49 patients (M:F 34:15, mean age 43 years) . The risk factors for mortality were analyzed. The reasons for uncontrollable bleed were : liver trauma (8), liver tumours (3), following liver transplantation (4), pancreatic necrosectomy (17) and miscellaneous causes (17). Results: There were 16 postoperative deaths (32.7%). On univariate analysis, hypovolaemic shock, a low urine output, raised INR, blood requirement of more than 6 units, hypothermia <340C, metabolic acidosis and sepsis were associated with an increased mortality. However, on multivariate logistic regression only hypothermia was significantly associated with mortality. Conclusion: A fair survival rate can be achieved by early and judicious use of abdominal packing especially before hypothermia supervenes.

Application of retroperitoneal pancreatic necrosectomy using percutaneous nephroscope / 中华肝胆外科杂志

Objective Infected pancreatic necrosis is a serious complication of necrotizing pancreatitis. A method of minimally-invasive retroperitoneal infected pancreatic necrosectomy using percutaneous nephroscope was evaluated. Methods 21 patients with acute pancreatitis were treated in our hospital from June 2008 to August 2009. Among 13 patients who developed infected pancreatic necrosis, 6 underwent percutaneous catheter drainage by CT guidance. Then retroperitoneal infected pancreatic necrostectomy using percutaneous nephroscope along the sinus tract were performed after drainage for 5-36 d. Results In these 6 patients, 3 received percutaneous nephroscopic treatment one time, 2 two times and 1 three times. There were no operative mortality and morbidity except that 1 patient developed pseudocyst 6 months after operation. Conclusion Retroperitoneal pancreatic necrosectomy by percutaneous nephroscope is a safe, feasible, minimally-invasive and efficient method for treating infected pancreatic necrosis when the indication and occasion are suitable. This method would be a valid therapeutic option for treating necrotizing pancreatitis. However, further evaluation is necessary.
